London's Sky Turned Orange Because of Hurricane Ophelia

On Monday, there was a red sun and an orange sky over parts of the U.K., but no need to panic—the apocalypse isn't quite here just yet. Rather, the U.K. experienced this phenomenon as a side effect of the natural disasters devastating other parts of Europe.

As wildfires rage across Portugal and northwest Spain, CNN reports that winds from Hurricane Ophelia are carrying smoke and debris from the blaze—plus some sand from the Sahara—up north. The result? A sky tinted anywhere from a light sepia to a dark, murky orange, complete with a glowing crimson sun.

Given that the air is expected to clear on Tuesday, social media users were quick to snap photographic evidence of the unusual sight and get #redsun trending on Twitter. The requisite Armageddon jokes were made, while some even made comparisons to Blade Runner 2049, Mad Max, and Donald Trump. Others wondered if it was an omen foretelling divine punishment for Brexit, while many welcomed the "spooky but stunning" view.

Regardless of whether you think the red sun is creepy or cool, you should take precautions before going outside to ogle. According to The Sun, the dust and particles responsible for the sky's eerie hue could exacerbate breathing problems for those already experiencing respiratory issues. So while you may feel inclined to Instagram this rare phenomenon, as with an eclipse, it might be safer to sit this one out and live vicariously through social media. Or a local showing of Blade Runner 2049, that is.
